Rek'sai needs a rework

I know, she is quite a new champion, but her design is one of the unhealthiest in the game. Thematically, she is supposed to be this underground assassin that comes out of the ground and eats your ass, but in game she is just a knock up bot. That's it. Press W. This way she is either gonna be decent in SoloQ and pick-or-ban in competitive, or trash in SoloQ and competitive. Her underground Q should have a bonus AD ratio, her W should have its knock up removed but have some new effect that fits with her assassin-like theme, her underground E should be faster and more fluid while making Rek'sai untargetable while in the tunnel, her normal Q and E need some tweaks and then her ult passive attackspeed needs to be removed in favor of something else. This is just a suggestion, im pretty sure if Riot reworks her it would be in a different way but you can't deny the truth. She is unhealthy, her theme doesn't fit her gameplay and she needs a rework. RITO PLS

EDIT: No part of her kit says asssassin, but her theme does. Also competitive makes her unhealthy, so Riot has to make her bad in normal play.
